7 Claims.

This invention relates to cover means for use in connection with handstamps and other devices, to enclose or cover identifying elements forsuch devices, and also relates to the method and means of securing thecover members to such devices.

This application is a division of my copending application for Stamp,Serial No. 452,844, filed May 16, 1930.

One of the main objects of my invention is to provide a cover member forthe protection of an insert utilized for identifying the device withwhich it is associated, the cover functioning to exclude dust, moistureand other foreign materials.

A further object of my invention is to provide an improved method andmeans for securing a suitable transparent cover member, of celluloid orlike material, to a device such as the wooden mounting block of a stamp.

Further objects and advantages of my invention will appear in thefollowing detailed description, reference being had to the accompanyingdrawing.

In the drawing:

Figure 1 is an end elevational view of a stamping device having a covermember applied to the mounting block thereof, in accordance with myinvention, to protect the stamp identifying means;

Figure 2 is an enlarged fragmentary side view of the block illustratingthe method of securing the cover member thereto;

Figure 3 is a fragmentary sectional view taken substantially along theplane of line 33 of Figure 2, on an enlarged scale; and

Figure 4 is a fragmentary view of a stamping device embodying a modifiedform of my in vention.

I have illustrated my invention, by way of example, as applied to astamp which comprises a mounting block 1, conveniently formed of wood, abed 2 of sponge rubber, or other suitable material, set into theunderface of the block, and a stamping element 8 suitably secured to thebed 2 and bearing suitable characters thereon for printing upon surfacesof articles which it is desired to mark in a suitable manner. The block1 is provided, at the sides thereof and near its upper face, with twolongitudinally extending grooves 4, which may be formed in any suitablemanner. This block may readily be produced from a suitable length ofwood in the nature of a moulding, having one face cut out or grooved toprovide the recess for reception of bed 2, and provided with the grooves4. A length of moulding thus formed can readily be cut into suitablelengths to provide blocks similar to the block 1, thus facilitatingproduction of such blocks with a corresponding saving in, the costthereof.

Block 1 is bored out from its upper face, centrally thereof, to providea socket 5 adapted for reception of a reduced stud 6 at the lower end ofa suitably shaped handle 7. The stud 6 has, a friction fit in the socket5 for securing the block 1 to the handle. Stamps of this general typeare well known in the art and the manner of use thereof need not beillustrated nor described in detail.

It is frequently necessary to use stamps of this general character andwhich bear different legends, a plurality of such stamps being commonlysupported in a rack or other suitable means. The general appearance ofthe stamps are quite similar and, in many cases, practically identical,so that it is necessary to view carefully a selected stamp before usingthe same, to be certain that this stamp bears the desired marking orlegend. This necessity for carefully consid-. ering the stamps beforeusing them, is conductive to error, as well as causing appreciable lossof time and inconvenience. It is desirable that the individual stamps bemarked for indicating clearly the legends or markings thereof.

The means for identifying the individual stamps should readily bevisible when the stamp is in its normal position of use or is supportedin a rack or other means, and should be capable of being applied to thestamp at small cost and without necessitating any material changestherein.

Referring more particularly to Figures 1 and 3, I provide an insert 8which conforms to the shape of the top or upper face of the block 1, andin the particular embodiment illustrated the latter is of substantiallyrectangular shape and has rounded corners. This insert may convenientlybe formed of paper, cardboard or other suitable material. The insert 8is confined between the upper face of the block 1 and a cover member 9.This cover member is preferably formed of a suitable transparentmaterial, such as transparent celluloid.

The cover member 9 is provided, at each side thereof, with a channelelement 10 which is so shaped as to fit closely about the rounded uppercorners of the block 1 with the inwardly projecting flanges 11 fittingsnugly into the grooves 4. This cover member is positioned upon theblock 1 by being slid on to the same lengthwise thereof, with thechannel elements 10 engaging about the. rounded edges of said block andthe inwardly projecting flanges 11 extending into the grooves 4. Inapplying the cover member it is not essential that it be slid lengthwiseonto the block, as this member may readily be applied by first engagingone of the flanges 11 into its cooperating groove 4, and then fittingthe cover member over the block, the other flange snapping into itsgroove due to the resiliency of the cover member. The cover member isheld against endwise movement by reason of the snugness with which theinwardly extending flanges 11 of the cover engage within the grooves 4of the block 1.

The insert 8 bears upon its upper face suitable markings or charactersfor identifying the stamp with which such insert is associated.Preferably, the identifying data upon the insert corresponds to theprinting element 3 of the stamp. The identifying data upon the insert 8is readily visible through the transparent cover member 9 and the insertis so disposed that the arrangement of the data thereon corresponds tothe arrangement of the corresponding printing element of the stamp. Theinsert thus serves not only to identify the stamp but also to indicatewhether the stamp is being held properly for printing the desired legendupon an article in proper relation thereto. Marking the stamping devicein this manner is highly advantageous as rendering it possible toascertain at a glance the particular stamp desired and, also, todetermine whether the stamp is being held in proper position forprinting therewith upon an article in proper relation thereto.

The insert 8 and the cover member 9 are provided with aligned openings,which are disposed in register with each other and with socket 5 ofblock 1. The stud 6 passes through these openings in the insert and thecover member, and serves to effectively secure them against movementrelative to each other and to block 1. When the handle '7 is detachedfrom block 1 for placing the stamp and handle in a kit which may beprovided for this purpose, the insert 8 is retained in position upon theblock 1 and in proper relation thereto by the cover member 9. Underordinary conditions, however, the handle 7 will remain in position andsecured to block 1, as in Figuure 1 of the drawing.

The cover 9 is preferably made of transparent material, as above stated.This is not essential, however, and the cover member may be made of anysuitable material rendered transparent for a suflicient portion of itsarea to enable the data upon the insert 8 to be viewed readily. Obvious-1y, if the cover member be formed of opaque material, the desiredresults can be accomplished by removing or cutting away suitableportions of the cover member. Preferably the cover member and the insertare disposed upon the top or upper face of the block 1. This is notessential, however, and my invention contemplates, in its broaderaspects, any other suitable or preferred arrangement of the cover memberand the insert. My invention utilizes the means for securing the handleto the block for also securing the insert and the cover member againstmovement relative to each other and to the block, though this is notessential in all instances since the cover member may be relied upon forholding the insert in position.

Referring now to Figures 2 and 3, the method of securing the covermember 9 to the block is illustrated. This method comprises using aheated needle point 13 or other suitable instrument and forcing itthrough the celluloid cover member 9 into the wood block 1. This securesperfect adhesion between the celluloid and the fibers of the wood, as at14 in Figures 2 and 3, and affords a very simple and inexpensive meth-0d of securing the celluloid to the wood without the use of anycementitious material, which would involve increased expense.

When using this method for securing the cover to the block, the covermember may be of the form described, or of any other suitable orpreferred form. It is also apparent that when the cover member issecured to the block at the points 14, flanges 11 and the grooves 4 maybe omitted, as shown in Figure 4. In Figure 4 a cover member 9a is shownwhich comprises a flat piece of suitable size and shape, which issecured over the insert 8 and to the block by the needle point methodabove described.

In a stamping device, the insert member need not ordinarily be changedor replaced, but in other devices it may be desirable to have inter-10ochangeable and renewable inserts. Obviously, the cover member when oncefastened to a device will always remain in place thereon. Therefore, toremove an insert from under the cover member, another insert or othersuitable card may be slipped under the edge of the cover member to forcethe insert thereunder outwardly for removal.

The foregoing description has been more specifically confined to theapplication of a cover 119 member to a stamping device, but it is to beunderstood, that this is only by way of example and that the covermember may be used in connection with a variety of articles. Also, thema-- 7 terials employed may vary, provided they are of such character asto cooperate in the manner above set forth, considered broadly, forsecuring the cover member to its associated support. I do not,therefore, intend to be strictly limited to the hereinbefore describedmethod and means, 1 except only in so far as the appended claims are solimited.

What I claim is:

1. The method of securing a celluloid cover member to a supportingmember, consisting in' 1 disposing the two members in adjoiningpositions, piercing said cover member by a pointed instrument andforcing a portion of the cover member into said supporting member, saidinstrument being heated to cause the portion of the cover forced intothe supporting member to fuse and adhere to the inner walls of thedepressions so formed in the supporting member.

2. The method of securing together two members, which comprisesdisposing the two members in adjoining positions, piercing both membersby heated piercing means and thereby forcing portions of one member intothe other member, said one member being fusible by heat derived from thepiercing means, and fusing said 143 pierced portions of the fusiblemember during the piercing operation to cause said portions of thefusible member to adhere to the other memher.

4. The method of securing together two members one of which is offusible material, which comprises disposing the twomembers in adjoiningpositions, piercing both members by heated piercing means andsimultaneously fusing the pierced portions of the fusible member by heatderived from the piercing means, thereby forcing the pierced portions ofone member into the other member and causing the pierced portions ofsaid fusible member to adhere to the other member.

5. The method of securing a celluloid cover member to a ligneoussupporting block, which comprises disposing said member and the block inadjoining positions, piercing both members by an instrument heated to aproper temperature to cause fusing of the celluloid, thereby forcinginto the block portions of the cover and simultaneously fusing saidportions of the cover to cause them to adhere to the block.

6. The method of securing together two members one of which is offusible material, which comprises disposing the two members in adjoiningpositions, piercing both members and simultaneously fusing the piercedportions of the fusible member, thereby forcing the pierced portions ofone member into the other member and causing the pierced portions ofsaid members to adhere together.

7. The method of securing together two members one of which is ofreadily fusible material analogous to celluloid, which comprisesdisposing the two members in adjoining positions, piercing both membersby heated piercing means and thereby forcing portions of one member intothe other member, and fusing the pierced portions of the fusible memberby heat derived from the piercing means and causing the pierced portionsof said members to adhere together.
